I'm thinking that you actually have the 125 cc version . There's no way anyone here is going to give you a definitive answer . I suggest that you buy a few sizes of jet and simply experiment until you achieve the optimum performance . I think you are already aware that if you produce more power you will have to change the rollers to make best use of it . Good luck.

With the greatest of respect , and it's got nothing to do with it being a Chinese scooter , I really don't think that you are going to get any specific answers from this forum . I've had a look at what performance upgrades are available for your scooter on eBay and I have to say I'm very surprised at how much is available and how cheap it is . High performance carbs and racing belt and roller kits are available so I'm guessing that these are the missing parts of the jigsaw . You would be much better off joining a FB group that's devoted to scooter tuning to be honest .
